.

d.

Fit the plate

of the tool [SST: — (Mot. 1972)] on the cylinder

block without tighten the bolts

e.

Fit the piece of the tool [SST: — (Mot. 1972)] in the push-rod of
the tool [SST: — (Mot. 1972)].
• Place the “end piece - pushrod”

assembly of the tool [SST:

— (Mot. 1972)] in the plate to centre the plate above the open-
ing of the oil jet.

• Tighten the plate bolts.
• Remove the “end piece - pushrod” assembly from the plate.

f.

Insert the oil jet in the pushrod.
• Place the “pushrod - oil jet” assembly in the plate by present-

ing the jet in front of its opening.

• Fit the system nut-screw

on the plate.

• Tighten the bolt

to has retaining wall of the pushrod on the

• Secure the flush bearing shell and push from the opposite side

the position of the bearing shell flush with the bearing.

c.

Measure the distance (X1) between the bearing face

and the edge of the bearing shell at points

,

and

using a depth gauge.

d.

If necessary, adjust the position of the bearing shell to the value (X1) = [179 mm (7.0 in)].

e.

Repeat the previous operations for the bearing shells of the bearings No 2, 4 and 5.

f.

If necessary, adjust the position of the bearing shells:
- of bearings No. 2 and 4 to the value (X2) = [88 mm (3.5 in)].

- of the bearing No. 5 to the value (X1) = [176 mm (6.9 in)].

g.

Secure the flush bearing shell against the rectified shimat
and push from the opposite side to position the bearing shell
flush with the bearing.

Place:

• a rectified shim

against the mating face of the crankshaft

thrust washer on bearing No.3

• the grooved bearing shell against the rectified shim.

h.

Measure the distance (X3) between the bearing face of the
thrust washer and the bearing shell edge using a depth gauge.

i.

Center the grooved bearing shell on the bearing, aligning the
shell with the hole groove.
• Adjust the position of the bearing shell at points

,

and

using the rectified shim

and a set of feeler gauges (thick-

ness of the shim

= (X3): [2 mm (0.1 in)].

j.

Secure the flush bearing shell with the bearing cap at

and

push from the opposite side to bring the bearing shell flush with
the bearing cap.

Place:

• the bearing cap on a bench,

k.

Measure the distance (X4) between the edge of the bearing
shell and the wall of the bearing cap at points

,

and

using a depth gauge.

l.

Adjust the position of the bearing shell at point

,

and using

a set of feeler gauges (feeler gauges (thickness of the shim

=

X4: [2 mm (0.1 in)]
• Repeat the previous operations for the other bearing caps.

m. Position the crankshaft thrust washers on the cylinder block

(washer plug

in the cylinder block notch)

• Use engine oil to lubricate the crankshaft journal bearing

shells and thrust washers (only the face making contact with
the crankshaft).

NOTE:
Ensure the bearing shells and the thrust washers do not move
when refitting the crankshaft and bearing caps.

4.

Install crankshaft, the bearing caps and the crankshaft bearing bolts.
NOTE:
Check that the bearing caps are in contact with the cylinder block before tightening the bearing cap bolts.

5.

Install main bearing caps with the following procedure:
